Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a plate filter for water-based paint. Background Art

[0002] Water-based paint is a paint that uses water as a solvent or dispersion medium. It has excellent non-stickiness and durability. In the production process of water-based paint, in order to facilitate the screening of large impurities or undissolved raw materials in the paint, it is usually necessary to use filtering equipment such as plate filters to filter the water-based paint.

[0003] According to patent publication number CN220176269U: the utility model belongs to the technical field of water-based paint production, in particular to a plate filter for water-based paint, including a chassis, two guide pipes are fixedly provided on the top of the chassis, a sealing cover is provided on the top of the guide pipe, an inspection door is provided on the front of the chassis, and a discharge valve is fixedly provided on the bottom of the chassis. The utility model is provided with components such as a drive motor, a rotating shaft, a push rod, a mounting plate and a spring. When performing a filtering operation, the rotation of the drive motor will drive the rotating shaft, and the rotating shaft will drive the two push rods. The push rods squeeze the mounting frame at the bottom, and the mounting frame squeezes the spring at the bottom. When the push rod is out of contact with the mounting frame, multiple springs apply thrust to the mounting frame to eject the mounting frame upward. Due to the continuous rotation of the rotating shaft, the frequent squeezing of the mounting frame by the push rod will cause it to be in a vibrating state, and impurities blocked in the filter holes of the filter plate will be shaken up, which can effectively prevent the equipment from being blocked and unable to be used normally.

[0004] However, there is a certain gap between the installation frame and the filter screen in the above patent, so the water-based paint is easy to drip onto the installation frame when adding, which makes the installation frame difficult to clean and reduces the filtering effect.

[0028] The main unit 100 includes a body 101, a feed pipe 102 is provided on the top of the body 101, and a discharge pipe 103 is provided on the lower side of the body 101;

[0029] The filter unit 200 includes a coarse filter fixing frame 201 and a fine filter fixing frame 202 with the same structure but different filter apertures. The coarse filter fixing frame 201 and the fine filter fixing frame 202 are respectively arranged at the upper and lower parts of the body 101. Two sets of drive components 204 are arranged on the inner wall of the body 101. A baffle 205 is arranged on the outer side of the drive component 204 to prevent paint from dripping onto the fixing frame.

[0030] Among them, a pulling plate for easy pulling is provided on the front of the coarse filter fixing frame 201, and a mounting hole 201a is opened on the front of the pulling plate. The mounting hole 201a is connected to the outer wall of the body 101 through bolts, so that the coarse filter fixing frame 201 is installed and fixed. A filter 201b is provided inside the coarse filter fixing frame 201, and a first tooth groove 201c is opened on the top rear side of the coarse filter fixing frame 201.

[0031] Furthermore, the driving assembly 204 includes a shell 204a with a beveled edge on the front side, the shell 204a is internally rotatably connected to a torsion spring shaft 204b, the outer wall of the torsion spring shaft 204b is fixedly connected to a gear 204c, the gear 204c is meshingly connected to the first tooth groove 201c, and the coarse filter fixing frame 201 drives the gear 204c to rotate after contacting the gear 204c through the first tooth groove 201c, thereby driving the torsion spring shaft 204b to rotate.

[0032] Furthermore, the baffle 205 is inclined and has the same inclination as the shell 204a. A second tooth groove 205b is provided on the rear side of the baffle 205. The second tooth groove 205b is meshed with the gear 204c. The gear 204c drives the second tooth groove 205b to move, thereby driving the baffle 205 to move.

[0033] Furthermore, a slider 205a with an I-shaped cross-section is fixedly connected to the rear side of the baffle 205, and a slide groove movably connected to the slider 205a is provided on the front side of the shell 204a, so that the baffle 205 is prevented from being separated from the shell 204a by the slider 205a and the slide groove.

[0034] Furthermore, four limit rods 203 are fixedly connected to the left and right sides of the inner wall of the body 101, the spacing between the opposite surfaces of two adjacent limit rods 203 on the same side is the same as the height of the coarse filter screen fixing frame 201, the lower limit rod 203 is the same width as one side of the coarse filter screen fixing frame 201, and the upper limit rod 203 extends inwardly to a greater extent than the lower limit rod 203, the upper limit rod 203 is used to prevent paint from dripping on the top of the coarse filter screen fixing frame 201, and the coarse filter screen fixing frame 201 is fixed by two upper and lower limit rods 203 on both sides to prevent the coarse filter screen fixing frame 201 from tilting.

[0035] During use, the coarse filter fixing frame 201 is inserted between the limit rods 203. As the coarse filter fixing frame 201 is pushed backward, the first tooth groove 201c drives the gear 204c to rotate. At the same time, the gear 204c drives the second tooth groove 205b to move and drives the baffle 205 to move downward. Then, the coarse filter fixing frame 201 is fixed by bolts, and the fine filter fixing frame 202 is fixed by the same operation. The limit rods 203 and the baffle 205 cooperate to prevent paint from dripping on the top of the fixing frame, thereby facilitating the cleaning of the fixing frame and preventing missed paint from being filtered by the filter 201b, thereby improving the filtering effect. The coarse filter fixing frame 201 is removed by the opposite operation, and the baffle 205 is reset by the rebound of the torsion spring shaft 204b and prevented from falling down on its own.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
